Description

本発明は、サイドウォール部に設けた標章の視認性を向上させたタイヤに関する。   The present invention relates to a tire in which the visibility of a mark provided on a sidewall portion is improved.

タイヤのサイドウォール部の表面には、タイヤのメーカ名、ブランド名、サイズ等を表す文字、記号などである標章が形成されている。そして、これら標章の視認性を高めるために、例えば、標章をサイドウォール部の表面よりも一段高く形成するとともに、標章の表面にリッジを設けることなどが行われている（例えば特許文献１参照）。   On the surface of the sidewall portion of the tire, a mark is formed which is a letter, symbol or the like representing a tire manufacturer's name, brand name, size or the like. Then, in order to increase the visibility of these marks, for example, the marks are formed one step higher than the surface of the sidewall portion, and a ridge is provided on the surface of the marks (eg, patent documents 1).

しかしながら従来の標章は、高さが一定であるため、例えその表面にリッジを形成した場合にも、外観が単調でありかつコントラストの変化も少ない。そのため視認性を十分に高めることはできなかった。   However, since the conventional mark has a constant height, even when a ridge is formed on the surface, the appearance is monotonous and the change in contrast is small. Therefore, the visibility could not be sufficiently improved.

本発明は、標章の外観に変化を与えて意匠性を高めるとともに、標章の表面と基準面との間のコントラストに大きな差をもたらして視認性を向上させうるタイヤを提供することを課題としている。   It is an object of the present invention to provide a tire that can change the appearance of a mark to enhance the design, as well as provide a large difference in the contrast between the surface of the mark and the reference surface to improve the visibility. And

本発明は、サイドウォール部に、１以上の標章を有する標章表示部が形成されたタイヤであって、
前記標章表示部は、前記サイドウォール部の表面に設けられる基準面と、この基準面に形成される前記標章とを具え、
前記標章は、その表面が前記基準面に対してタイヤ半径方向に傾斜し、
かつ前記標章は、前記標章の表面が前記基準面よりも低いタイヤ半径方向一方側の凹部と、前記標章の表面が前記基準面よりも高いタイヤ半径方向他方側の凸部とを具える。 The present invention is a tire in which a mark display portion having one or more marks is formed on a side wall portion,
The mark display portion includes a reference surface provided on the surface of the sidewall portion, and the mark formed on the reference surface.
The mark is inclined in the tire radial direction with respect to the reference surface.
And, the mark has a concave portion on one side in the tire radial direction whose surface of the mark is lower than the reference surface, and a convex portion on the other side in the tire radial direction whose surface of the mark is higher than the reference surface. I see.

本発明に係るタイヤでは、前記標章表示部は、前記サイドウォール部の表面から一定高さで突出する台座部を具え、この台座部の表面が前記基準面を形成するのが好ましい。   In the tire according to the present invention, it is preferable that the mark display unit includes a pedestal projecting at a fixed height from the surface of the sidewall, and the surface of the pedestal forms the reference surface.

本発明に係るタイヤでは、前記凹部の最大深さ部分における前記基準面からの深さは、前記サイドウォール部の表面からの前記台座部の高さ以下であるのが好ましい。   In the tire according to the present invention, the depth from the reference surface in the maximum depth portion of the recess is preferably equal to or less than the height of the pedestal from the surface of the sidewall.

本発明に係るタイヤでは、前記凹部の最大深さ部分における前記基準面からの深さは、前記凸部の最大高さ部分における前記基準面からの高さの０．８〜１．２倍であるのが好ましい。   In the tire according to the present invention, the depth from the reference surface in the maximum depth portion of the recess is 0.8 to 1.2 times the height from the reference surface in the maximum height portion of the protrusion. Preferably there.

本発明に係るタイヤでは、前記標章表示部は、前記基準面又は前記標章の表面の一方に、複数の小突起部を具え、
前記小突起部は、最大太さが５０〜１０００μm、突出高さが５０〜１０００μm、かつ隣り合う小突起部間の中心間距離が２００〜１０００μmであるのが好ましい。 In the tire according to the present invention, the mark display unit includes a plurality of small protrusions on one of the reference surface or the surface of the mark.
The small projections preferably have a maximum thickness of 50 to 1000 μm, a projection height of 50 to 1000 μm, and a center-to-center distance between adjacent small projections of 200 to 1000 μm.

本発明に係るタイヤでは、前記小突起部は、上端側が小径をなす円錐台状をなすのが好ましい。   In the tire according to the present invention, it is preferable that the small projection has a truncated cone shape whose upper end side has a small diameter.

本発明は、基準面に形成される標章の表面が、基準面に対してタイヤ半径方向に傾斜している。そしてこの傾斜により、標章に、基準面よりも低い凹部と高い凸部とが形成される。そのため標章の外観に変化を与えることができ、意匠性を高めうる。   In the present invention, the surface of the mark formed on the reference surface is inclined in the tire radial direction with respect to the reference surface. And by this inclination, the recessed part lower than a reference plane and a high convex part are formed in a mark. Therefore, the appearance of the mark can be changed, and the design can be enhanced.

又標章は、その表面が傾斜することで、基準面との間で光の反射の仕方を相違させることができ、コントラストを高めうる。しかも標章は、凹部と凸部とにより、陰影に大きな変化をもたらすとともに、立体感を高めることができる。そしてこれらの相乗効果によって、標章の視認性を向上させることができる。   Also, the mark can be made to reflect light differently from the reference surface by the inclination of the surface, which can enhance the contrast. Moreover, the mark can bring about a large change in the shadow and can enhance the three-dimensional effect by the concave portion and the convex portion. And these synergetic effects can improve the visibility of the mark.

以下、本発明の実施の形態について、詳細に説明する。
図１に示すように、本実施形態のタイヤ１は、少なくとも一方のサイドウォール部２に、１以上の標章表示部３が配される。 Hereinafter, embodiments of the present invention will be described in detail.
As shown in FIG. 1, in the tire 1 of the present embodiment, at least one sidewall portion 2 is provided with one or more mark display portions 3.

標章表示部３は、サイドウォール部２の表面２ｓに設けられる基準面Ｘと、この基準面Ｘに形成される１以上の標章４とを具える。本例では、標章表示部３は、サイドウォール部２の表面２ｓから一定の高さＨ５で段差状に突出する台座部５を具え、この台座部５の表面５ｓが前記基準面Ｘを形成する。   The mark display unit 3 includes a reference surface X provided on the surface 2s of the sidewall portion 2 and one or more marks 4 formed on the reference surface X. In this example, the mark display unit 3 includes a pedestal 5 protruding in a step-like manner at a constant height H5 from the surface 2s of the sidewall 2, and the surface 5s of the pedestal 5 forms the reference plane X. Do.

標章４は、タイヤのメーカ名、ブランド名、サイズ等を表すための文字、記号、図形などであり、本例では、基準面Ｘに、複数の標章４からなるブランド名が形成されている場合が示される。   Marks 4 are characters, symbols, figures, etc. for representing a tire manufacturer name, brand name, size, etc. In this example, a brand name consisting of a plurality of marks 4 is formed on the reference surface X. Case is shown.

図２、３に示すように、標章４の表面４ｓは、基準面Ｘに対してタイヤ半径方向に傾斜する。そしてこの傾斜により、標章４には、表面４ｓが基準面Ｘよりも低くなる凹部６と、表面４ｓが基準面Ｘよりも高くなる凸部７とが設けられる。凹部６は、タイヤ半径方向一方側（図では半径方向内側）に配され、凸部７は、タイヤ半径方向他方側（図では半径方向外側）に配される。凹部６と凸部７との境界８は、基準面Ｘと同高さである。本例では、前記境界８はタイヤ周方向にのびる。   As shown in FIGS. 2 and 3, the surface 4 s of the mark 4 is inclined in the tire radial direction with respect to the reference surface X. Then, due to this inclination, the mark 4 is provided with a recess 6 in which the surface 4 s is lower than the reference surface X and a protrusion 7 in which the surface 4 s is higher than the reference surface X. The concave portion 6 is disposed on one side (radially inner side in the drawing) in the tire radial direction, and the convex portion 7 is disposed on the other side (radially outer side in the drawing) in the tire radial direction. The boundary 8 between the concave portion 6 and the convex portion 7 has the same height as the reference plane X. In the present example, the boundary 8 extends in the tire circumferential direction.

このように標章４の表面４ｓが傾斜し、かつ凹部６と凸部７とが形成されることにより、標章４の一部が台座部５に埋まったような新規なデザインとなり、標章４の外観に変化を与え、意匠性を高めることができる。又標章４の表面４ｓが傾斜することで、基準面Ｘとの間で光の反射の仕方を相違させることができ、コントラスト（明暗の差）を高めうる。しかも標章４は、凹部６と凸部７とにより、陰影に大きな変化をもたらすとともに、立体感を高めることができる。そしてこれらの相乗効果によって、標章４の視認性を向上させることができる。   Thus, the surface 4s of the mark 4 is inclined, and the concave portion 6 and the convex portion 7 are formed, thereby providing a novel design in which a part of the mark 4 is buried in the pedestal portion 5, and the mark The appearance of 4 can be changed to enhance the design. In addition, the inclination of the surface 4s of the mark 4 makes it possible to differ the way of light reflection from the reference surface X, and to enhance the contrast (difference between light and dark). Moreover, the mark 4 can make a large change in the shadow and can enhance the three-dimensional effect by the concave portion 6 and the convex portion 7. And the synergetic effect of these can improve the visibility of the mark 4.

図３に示すように、本例では、凹部６の最大深さ部分６ｅにおける基準面Ｘからの深さＤ６は、サイドウォール部２の表面２ｓからの台座部５の高さＨ５以下である。本例では Ｄ６＜Ｈ５ の場合が示される。これにより、最大深さ部分６ｅにおけるサイドウォールゴムのゲージ厚さを、標章表示部３以外の部分におけるサイドウォールゴムのゲージ厚さ以上に確保することができ、凹部６に起因する損傷を抑制することができる。   As shown in FIG. 3, in this example, the depth D6 from the reference plane X in the maximum depth portion 6e of the recess 6 is equal to or less than the height H5 of the pedestal portion 5 from the surface 2s of the sidewall portion 2. In this example, the case of D6 <H5 is shown. Thereby, the gauge thickness of the sidewall rubber in the maximum depth portion 6 e can be ensured to be equal to or larger than the gauge thickness of the sidewall rubber in the portion other than the mark display portion 3, and the damage due to the recess 6 is suppressed. can do.

前記深さＤ６は、凸部７の最大高さ部分７ｅにおける基準面Ｘからの高さＨ７の０．８〜１．２倍、即ちＤ６とＨ７とがほぼ等しいことが好ましい。これにより凹部６と凸部７との配分をバランス化し、視認性の向上効果を高めうる。同様の理由により、前記境界８は、標章４におけるタイヤ半径方向一方側の端部ＥＡからのタイヤ半径方向距離ＬＡが、タイヤ半径方向他方側の端部ＥＢからのタイヤ半径方向距離ＬＢの０．８〜１．２倍であるのも好ましい。   The depth D6 is preferably 0.8 to 1.2 times the height H7 from the reference plane X at the maximum height portion 7e of the convex portion 7, that is, D6 and H7 are substantially equal. Thereby, the distribution of the concave portion 6 and the convex portion 7 can be balanced, and the improvement effect of the visibility can be enhanced. For the same reason, the boundary 8 is defined as the tire radial direction distance LA from the tire radial direction end EA of the mark 4 to 0 of the tire radial direction distance LB from the tire radial direction other end EB. It is also preferable that it is .8 to 1.2 times.

ここで、前記端部ＥＡは、標章４のうちで最もタイヤ半径方向一方側に位置する端部を意味し、端部ＥＢは、標章４のうちで最もタイヤ半径方向他方側に位置する端部を意味する。また凹部６の最大深さ部分６ｅは、前記端部ＥＡの位置に形成され、凸部７の最大高さ部分７ｅは、前記端部ＥＢの位置に形成される。   Here, the end EA means an end of the marks 4 located most on one side in the tire radial direction, and the end EB is located most on the other side of the marks 4 in the tire radial direction Means the end. Further, the maximum depth portion 6e of the recess 6 is formed at the position of the end EA, and the maximum height portion 7e of the protrusion 7 is formed at the position of the end EB.

標章４の表面４ｓは、平面であるのが好ましいが、例えばタイヤ半径方向に円弧状に湾曲してのびる曲面であっても良い。   The surface 4s of the mark 4 is preferably a flat surface, but may be, for example, a curved surface extending in an arc shape in the radial direction of the tire.

又標章表示部３では、図４（Ａ）、（Ｂ）に示すように、基準面Ｘ又は標章４の表面４ｓのうちの一方の面Ｓに、この面Ｓから突出する複数の小突起部１５を具えることが好ましい。小突起部１５は、最大太さＤ１が５０〜１０００μm、前記面Ｓからの突出高さＨ１が５０〜１０００μm、かつ隣り合う小突起部１５、１５間の中心間距離Ｌ１が２００〜１０００μmであるのが好ましい。特には、小突起部１５は、上端側が小径をなす円錐台状をなすのがより好ましい。   In the mark display unit 3, as shown in FIGS. 4A and 4B, on the surface S of the reference surface X or one of the surfaces 4s of the mark 4, a plurality of small portions projecting from the surface S Preferably, the protrusions 15 are provided. The small protrusions 15 have a maximum thickness D1 of 50 to 1000 μm, a protrusion height H1 from the surface S of 50 to 1000 μm, and a center-to-center distance L1 between adjacent small protrusions 15 of 200 to 1000 μm. Is preferred. In particular, it is more preferable that the small protrusions 15 have a truncated cone shape whose upper end side has a small diameter.

このような小突起部１５は、光を乱反射させ、前記面Ｓ（基準面Ｘ又は標章４の表面４ｓ）を黒く見せることができる。その結果、標章４の輪郭形状をより明確化でき、標章４の視認性をさらに高めることができる。本発明者の研究の結果、小突起部１５の最大太さＤ１、突出高さＨ１、及び中心間距離Ｌ１が前記範囲を外れると、面Ｓが光の反射によって白っぽく見え、標章４と基準面Ｘとのコントラスト差が減じる傾向を招く。なお、小突起部１５が円錐台状とすることで、円柱状に比して強度を高めつつ光の反射をさらに抑えることができる。   Such small protrusions 15 diffusely reflect light and can make the surface S (the reference surface X or the surface 4s of the mark 4) appear black. As a result, the outline shape of the mark 4 can be further clarified, and the visibility of the mark 4 can be further enhanced. As a result of the present inventor's research, when the maximum thickness D1 of the small protrusion 15, the protrusion height H1, and the center distance L1 are out of the above range, the surface S looks whitish due to light reflection, and the mark 4 and the reference The contrast difference with the plane X tends to be reduced. In addition, by making the small protrusion 15 into a truncated cone shape, it is possible to further suppress the reflection of light while increasing the strength as compared to the cylindrical shape.

本例では小突起部１５が、碁盤目状に配列する場合が示されるが、千鳥状の配列でも良く、又中心間距離Ｌ１が前記範囲を満たすならばランダムに配列することもできる。   In this example, the small projections 15 are arranged in a grid, but they may be arranged in a zigzag or may be arranged randomly if the center-to-center distance L1 satisfies the above range.

標章表示部３では、台座部５を設けることなく、サイドウォール部２の表面２ｓに標章４を直接に形成することもできる。この場合、サイドウォール部２の表面２ｓが、基準面Ｘを構成する。このとき標章表示部３を他の領域と区別するため、サイドウォール部２の表面２ｓに、標章表示部３の周囲を囲む小高さのリブなどを設けることが好ましい。   In the mark display unit 3, the mark 4 can also be formed directly on the surface 2 s of the side wall portion 2 without providing the pedestal portion 5. In this case, the surface 2s of the sidewall portion 2 constitutes a reference plane X. At this time, in order to distinguish the mark display portion 3 from other regions, it is preferable to provide a rib or the like having a small height surrounding the periphery of the mark display portion 3 on the surface 2s of the sidewall portion 2.

以上、本発明の特に好ましい実施形態について詳述したが、本発明は図示の実施形態に限定されることなく、種々の態様に変形して実施しうる。   As mentioned above, although the especially preferable embodiment of this invention was explained in full detail, this invention can be deform | transformed into a various aspect, and can be implemented, without being limited to embodiment of illustration.

サイドウォール部の表面に標章表示部を表１の仕様で形成したタイヤを試作し、標章の視認性を比較した。台座部の高さは、各タイヤとも同一であり、又標章の台座部の表面（基準面Ｘ）からの突出高さ（標章の表面が傾斜する場合は、最大の突出高さ）は、各タイヤとも同一である。   The tire in which the mark display part was formed on the surface of the side wall part by the specification of Table 1 was made as an experiment, and the visibility of the mark was compared. The height of the pedestal is the same for each tire, and the protrusion height from the surface (reference surface X) of the pedestal of the mark (the maximum protrusion height when the surface of the mark is inclined) is , Each tire is the same.

比較例１において、標章は、台座部からの高さが一定である。比較例２において、標章の表面は傾斜しているが、標章全体が台座部から突出している。実施例１〜４において、凹部の最大深さ部分における深さＤ６は、台座部の高さＨ５以下である。   In Comparative Example 1, the height of the mark from the pedestal is constant. In Comparative Example 2, the surface of the mark is inclined, but the entire mark protrudes from the pedestal. In Embodiments 1 to 4, the depth D6 at the maximum depth portion of the recess is equal to or less than the height H5 of the pedestal.

比較例１、２、実施例１〜３において、標章の表面に小突起部を形成している。各タイヤとも、小突起部は円錐台状をなし、その最大太さＤ１は３２０μm、突出高さＨ１は５００μm、中心間距離Ｌ１は４００μmであった。   In Comparative Examples 1 and 2 and Examples 1 to 3, small projections are formed on the surface of the mark. In each tire, the small protrusions had a truncated cone shape, the maximum thickness D1 was 320 μm, the protruding height H1 was 500 μm, and the center-to-center distance L1 was 400 μm.

視認性は、目視による官能評価により比較例１を１００とする指数で評価した。数値が大なほど優れている。   Visibility was evaluated by an index where Comparative Example 1 is 100 by visual sensory evaluation. The numbers are great.
